rear deck speaker removal

i have a 1997 millenia l. just wondering how to remove the back speakers. are they 6x9 or 5x7 or what. I know one has a tear in it. They are pioneer speakers.
I need to remove the rear deck in the car to get to the speakers. I dont know how to do this. There is no glove box like the s series, just a tray.

Please help.

thanks

The rear speakers are 6 1/2 in. speakers. I have not looked at them yet, but i will let you know what i find.
